不発明は、割卵後の卵黄と卵白が部分的に混会した状態

ろる。DETAILED DESCRIPTION OF THE INVENTION The invention is directed to a detection device that optically detects a state in which the egg yolk and albumen are partially mixed after breaking the egg.
菓子がＡ、マヨネーズ類等の食品製造業では卵を原料と

Depending on the form of use, is it only the egg yolk that is used as the bulk material for these foods? There are three types: those that use only egg white, and those that use both egg yolk and egg white.

を図るものである。Here, when using in the former two usage forms, it is necessary to break one egg and separate it into egg yolk and egg white. Currently, this process #1 has been mechanized, and at the same time, the egg is automatically broken and the yolk and white are automatically separated. . At this time,
Sometimes the yolk and white are not completely separated, and some of the yolk gets mixed into the white, and this situation is conventionally called ``scattering.'' Eggs that have been exposed to this scattered light twice are inferior to raw materials made only of egg whites, and need to be removed before they are mixed into raw materials made only of egg whites. This removal was visually monitored by the American servant "H", and whenever a disturbed egg appeared, it was removed. Therefore, the speed at which eggs are broken by a machine is lower than the limit speed that humans can understand, resulting in a decrease in work efficiency.This invention did not study the above points, and The purpose is to speed up egg-breaking by detecting disordered fL egg trays logically.

。For this reason, the invention is to irradiate the egg white with ultraviolet rays, and as a result, remove the light other than the fluorescence emitted by the egg yolk using an optical filter.
'The light receiving element detects only the light that has passed through the electronics filter,
The number of grooves is determined so that the strength of the signal is compared with a predetermined comparison value to determine whether it is random or not.
以下不発明の一夾施例を図面に基いて詳述する。Hereinafter, one embodiment of the invention will be described in detail based on the drawings.
第１図は卵黄の螢光スペクトルを示したもので、卵黄に
紫外線全照射する２卵黄は螢光奮発する。Figure 1 shows the fluorescence spectrum of egg yolk.The egg yolk, which is fully irradiated with ultraviolet rays, becomes extremely fluorescent.

It is constructed as shown in Fig. 3.That is, the detection section includes a condenser lens 3a for condensing 3σ fluorescent light, an optical filter 3b that selectively transmits only the egg yolk fluorescence, and a transmitting filter.

As shown in the figure, it emits the characteristic fluorescence of egg yolk. After this fluorescent light is filtered by the light collecting rung 3a, only the fluorescent light of the yellow light is selectively transmitted through the optical lps Jb. . There is a correlation between the size of the egg mixed in the egg white and the size of the 11゜Kiba.
a) Comparison circuit P output to comparison circuit ≠ b after amplification
6'lbK is applied with the lower limit value set in advance in the comparison value setting section 4'C and which should be determined as a disordered egg.
This set value and the output value of the increase [1] circuit section aj are compared in the comparator circuit 4Ab, and when it is determined that the egg is disordered, the optical wavelength characteristic of the judgment signal section 3 is shown in the output section ga. It is comparable. Characteristic A indicated by a dotted line indicates the relative sensitivity of the light receiving element 3a, and characteristic B indicated by a solid line indicates the relative sensitivity of the optical filter 3.
It is the relative transmittance of b. As is clear from the figure, the wavelength peak value of the output characteristic B of the optical filter 3b closely matches the fluorescence spectrum of the egg leopard shown in Figure 1, and the value is about 520 nm. It becomes.

This means that if the fluorescent substance detected by using the optical filter 3b has a wavelength peak in a region other than the transmission band, the shadow will be completely reduced. It means everything.

This is what I took. As is clear from the figure, there is a correlation between the output ratio of the egg yolk mixed in the egg white and the normal egg white in the comparison circuit ≠b. Therefore, by setting the comparative value setting section 4'e for the output ratio Y corresponding to the amount X of mixed egg yolk that should be judged to be a random egg, the comparison circuit section Random fL eggs can be identified.
